Hello George, of course if should be possible to reflash a flash microcontroller, but honestly, how should the flash memory of the controller have been affected by the impact on the floor you told us about earlier?
If the 68HC05 (whatever it does in the PowerBook) is the cause of the trouble I would start looking for de-soldering of any of the contact legs! Uwe.
